Maybe the better route is to return it. You're correct, it's foolish to accept poor work. It would likely be less hassle for me to fix it myself, but in so doing, I'm supporting the practice of poor quality.
The problem with returning something for rework (besides the time)...is that it might come back
still not right. And possibly needing more work after the 'fix' than what it needs right now.
Sometimes it's better to just cut our losses, fix it ourselves, swallow hard, and file it away in our memory bank for the future.
There's an aluminum bedding block stock here now that's kind of the same situation. They always need some work, either lapping or on the mill. But this one is truly nasty...the block is in there crooked, down in the front
and down in the rear. As best I can tell from this lash up, the block itself is also twisted along it's length. It's advertised as a "6061 billet bedding block" which is a total marketing ploy meant to appeal to the 'bubble pack' consumer. It's actually a 6061
hardness piece of aluminum
extrusion. Now that's not totally bad, in and of itself. But it's not milled from a single chunk of 6061T6 tooling stock, as is implied. I guess the hunk of extruded aluminum is how they market it as a "billet".
But a little set up time and a 1.375 ball end mill will turn the turd into ice cream. I sure hope the trigger guard doesn't need any filing...that would rattle me.
Best of luck with your project. If I can be of any assistance, let me know sir.
Good shootin' -Al
